SAN BERNARDINO >> Residents of a usually quiet apartment complex in San Bernardino were shocked to learn a man was fatally stabbed early Wednesday morning in the building’s parking area.

“I heard sirens, but I didn’t think they were for here,” said Jonathan Nickson, 17, who lives with his family in the Lido complex, at 1265 Kendall Drive.

The Cajon High School student was on his way to school when he noticed the crime scene tape cordoning off a large portion of the parking area.

“Stuff like this usually doesn’t happen,” said Nickson as he put his earbuds back into his ears and walked off to get to school while detectives gathered evidence about 15 feet away.

Other residents, mostly parents taking their children to school, also expressed disbelief when they learned of the fatal stabbing. One mother said she heard a car alarm going off around 4:30 a.m. but didn’t think much of it.

Police received a call just before 4:30 a.m. reporting that a man was lying on the ground outside the complex, said Lt. Mike Madden, San Bernardino Police Department spokesman.

Paramedics took the man — only identified as a white man in his 50s — to an area hospital where he later died, initial reports indicate.

The unidentified man has a history of being transient but had been living with a roommate at the complex at the time of his death.

Police investigating the stabbing had few details. A motive for the attack is unclear, however officials say the assault does not appear to be random.
